Abstract
The TEM problem for a current loop centered on the axis of a conducting cylindrical layered magnet is solved using uniform codes that couple Tikhonov's method for horizontally homogeneous half-space and separation of variables. The transient response is investigated as a function of model parameters simulating a multistring well casing.
